FOREWORD 0.1 This Indian Standard was adopted by the Indian Standards Institution on 5 August 1966, after the draft finalized by the Rubber Products Sectional Committee had been approved by the Chemical Division Council. 0.2 Rubber ice .bags are manufactured by moulding and press curing in the country, though these are occasionally hand-made from cut sheets of rubber, elsewhere. These bags are commonly manufactured in round shape and red colour. Of late, oval shape ice bags are also finding their way into the market which may become popular since these are generally applied on the forehead. This standard covers both the types of ice bags, 0.3 Apart from the test for reaction to aqueous extract, there are no other requirements prescribed in this standard preventing the use of such ingredients in compounding of rubber which may cause irritation, chafing or contact dermatitis to the skin cqming in contact due to the obvious difficulties in either prescribing the composition of rubber or prescribing detailed chemical or physiological tests. It is however recommended that only ingredients, free from harmful substances liable to cause irritation, chafing or contact dermatitis, be used in the manufacture of.ice bags. 0.4 In the preparation of this standard, considerable derived from the following publications: assistance has been T-47-121-1946 Caoutchouc Vessies a glace moulees (Rubber ice bags ). Association Francise de Normalization. B.S.. 1898 : 1952 Specification for rubber ice bags for the hospital use. British Standards Institution.. ZZ-B-0045 a-1963 Bag, ice, rubber. US Federal Supply Services. 0.5 For the purpose of deciding whether a particular this standard is complied with, the final value;observed 3 requirement of or calculated, IS:3867-1966 expressing the result of a test or analysis, shall be rounded off in accordance with IS : 2-1960*. The number significant places retained in the rounded off value should be the same as that of the specified value in this standard. of 1. SCOPE 1.1 This standard prescribes the requirements and methods of sampling and tests for ice bags made from natural rubber or synthetic rubber, or a blend of the two. 2. TYPES 2.1 This specification covers two types of ice bags according shape and size, as follows: Type A Type B Round shape. Oval shape. to their 3. REQUIREMENTS 3.1 No cbmpounding ingredient shall be included which may be injurious or cause irritation to living human skin coming in contact with the finished bag. 3.2 The bags shall be round for type A and oval for type B with an opening in the centre for the closure and cap. The ice bags shall have smooth surfaces and all joitlts shall be made before vulcanization except the closure which may be fitted after vulcanization. The closures and caps shall be of non-rusting type. The closures shall have a groove on the outside, around its circumference. It shall be tightly and securely fixed to the mouth of the bag by two or more turns of galvanized mild steel wire, 0.45 to 0.47 mm, placed in line with groove. A layer of rubber-proofed fabric shall be placed between the rubber and wire and the whole neck&all finally be covered by a rubber sleeve. The rubberized fabric and, rubber sleeve shall be fixed using rubber solution and shall be of such size as to extend, throughout the height of the neck, up to the rim of the closure. The form and pitch of the screw threads on the cap and in the closure shall be such that the cap shall screw accurately along the whole length of the closure threads. The cap shaM be fitted with a suitable rubber washer. When the cap is screwed home, the flange of the cap shall press closely on to the rubber washer and provide a water-tight closure. The rubber of the sleeve and washer shall be of the same quality as that used in the body of the bag. *Rules for rounding off numerical values ( revised). 4 ls:3lM7-M6 3.3 Colour -The and the supplier. colour shall be as agreed to between the purchaser NOTE - For the sake of uniformity reddish pink colour which .is generally assooitited with the ice bags used in hospitals, is recommended. 3.4 Dimensions 3.4.1 The type 1 material shall have a diameter of 200 & 6 mm and closure opening of 50.0 f 0.5 mm ( nominal ).
